DOI: 10.1021/acs.organomet.7b00240
Abstract: We report the self-sensitized aerobic photooxidation of 2,5-diphenyltellurophene (PT). Irradiation of PT induces rapid intersystem crossing to the triplet excited state, which undergoes energy transfer to oxygen to form singlet oxygen. Reaction of the heterocycle… read more here.

DOI: 10.1021/acscatal.1c03949
Abstract: Chiral cis-cyclopropanes are strained rigid analogues of alkyl chains, whose study and application are limited by their difficult synthesis. A modular approach from olefin materials is enabled by the discovery of the electron donor–acceptor (EDA)… read more here.

DOI: 10.1038/s42004-020-0318-x
Abstract: C60 is regarded as the most efficient singlet oxygen (1O2) photosensitizer. Yet, its oxidation by self-sensitized 1O2 remains unclear. The literature hints both oxygen and C60 must be at excited states to react, implying a… read more here.

DOI: 10.1080/10717544.2022.2141920
Abstract: Abstract Photodynamic therapy (PDT) has been extensively investigated as a spatiotemporally noninvasive and controllable modality for cancer treatment. However, the intracellular antioxidant systems mainly consisting of thioredoxin (Trx) and glutathione (GSH) significantly counteract and prevent… read more here.
